DOOR-HOLDER.

SPECIFICATIONMformng part of Letters Patent 190,720,560, dated February 17, 1903.

Application filed October 9,1902. Serial No. 126,583. (No model.)

To all whom it may concern,.-

Beit known that I, JAMES R. CARROLL, a citizen of the United States, residing at Mc- Call, in the parish of Ascension and State of Louisiana, have invented a new and useful Door-Holder, of which the following is a speci` iication. e

This invention relates to door-stops.

The object of the Vinvention is to provide a door-stop which will in a positive manner hold the door open anydesired distance and which may be released 4to permit closing of the door by an inward or outward movement thereof. Y

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a door-stop, as will be hereinafter fully described and claimed. Y

In the accompanying drawings, forming a part of this specification, and' in which like numerals of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein eX- hibited may be varied or changed as to shape, proportion, and exact manner lof assemblage without departing from the spirit thereof.

In the drawings, Figurel is a view in side elevation, partly in section, of a door-stop constructed in accordance with the present invention, showing the same set or in position to hold the door open. Fig. 2 is a view in vertical section, .taken at right angles to Fig. 1. Fig. 3 is a View similar to Fig. 1, showing the position of the parts when the stop is tripped.

Referring to the drawings, 1 designates a bolt which is mounted for reciprocatory movement within a guide or casing 2, secured to a door by screws 3 passing through anges 4 on the guide. The boltis provided with a chamber 5 in oneside, and in this chamber and near the'upper end thereof is pivoted a' pawl 6, having intermediate of its ends a toe 7 to interlock with a shoulderl 8, formed in one edge of a plate 9, secured to the door back of the guide 2, the upper end of the plate being bent at right angles to its length to constitute a guide 10 for the shank 11 of the plate 9, so that when it comes opposite the shoulder it will immediately spring into engagement therewith. The lower terminal of the pawl'is curved to present-a cam-surface 15 to be engaged by a dog 16, carried by a lifter 17,

the lifter beingguided for operative movement -through the medium of a pin 18, Working in a slot 19 in the bolt l. Pivoted to the lower end of the bolt is a double-acting toe20, to the lower terminal of which is connected a buffer 21, constructed of rubber and being adapted by frictional contact with the i'loor of a room to hold the door open at the desired angle. The connection between the buer and the toe is effect ed in this instance through the medium of a screw 22, the head of which is housed in a socket 23 in the under side of the buffer, and its upperend is threaded intothetoe, a spring interposed between the lower terminal of the toeand the upper face of the bufferoperat- .ing to hold thelatter in yielding engagement with the floor. By the provision ofthe screw 22 the buffer may be adjusted from time to time to compensate for wear. The toe may be connected with the bolt in any preferred manner, and in this instance is shown as effected by providing the plate with a tongue 24 to fit in the recess 25 in the toe, a bolt 26 operating to hold the parts pivotally connected.

In the use of the device it is secured to the door in the manner described, with the buffer about three-fourths of an inch above the floor, and in order to permit the toe to have the requisite rocking movement tos release the pawl and also to allow the bolt to have the desired upward movement when released the door is cut away at 27 opposite thetoe and the lifter. When it is desired to'check the door at any particular point, the foot is placed upon the head of the shank and the bolt is pressed down until the toe of the pawl engages with the shoulder of the plate 9, this bolt, thereby to cause the toe 7 to bear against IOO movement of the bolt causing the buffer forcibly to contact with the floor. When the parts are in this position, the door will be held against closing or opening; but should it be desired to close or further open the door an inward or outward push thereon will cause the toe to be rocked to the position shown in full lines in Fig. 3, whereupon the dog will be raised and contact with the lower end of the pawl, thereby throwing the toe of the latter out of engagement with the shoulder' of the plate 9 and releasing the bolt.

It will be seen from the foregoing description that although the device of this invention is of exceedingly simple construction it will be found thoroughly effective and durable in use for the purpose designed and may be readily applied to position for use.

Having thus described the invention, what I claim isl. In a door-stop, the combination with a member adapted to be slidingly attached to a door and to move downward and upward, means for locking the same in its downward position to secure the door, and means actuated by a forcible movement of the door to automatically release the member and permit its upward movement to release the door.

2. In a door-stop, the combination with a member adapted to be slidingly attached to a door and to move downward and upward, means for locking the same in its downward position to secure the door, a reciprocatory lifter associated with the member and adapted for operation to automatically release the same, and a rocking member actuated by the movement of the door to operate the lifter.

3. A door-stop comprising abolt, a springpressed pawl carried thereby and provided with means to interlock with a part of a door to hold the bolt depressed, a reciprocatory lifter associated with the bolt and carryinga dog, and a double-acting toe carried by the bolt and adapted upon being rocked to lift the dog into engagement with the pawl to release the bolt.

4. A door-stop, comprising a guide adapted to be secured to a door, a bolt housed therein and provided with a chamber, a springpressed pawl pivoted within the chamber and having its lower terminal constituting a cam and provided intermediate of its length with a locking projection, a reoiprocatory lifter carried by the bolt, a dog carried by the lifter and adapted to release the pawl, a doubleacting toe carried by the lower end of the bolt, an adjustable spring-pressed buffer carried by the toe, and retracting means carried `by the upper end of the bolt.

In testimony that I claim the foregoing as my own I have hereto alixed my signature in the presence of two witnesses.
